Pete, At the time this holster was made there was likely no "factory" in the mass sense of the word. In the turn of the Century there was a great deal of pride of workmanship not seen in the last 50 years or so. I doubt this could have gone un noticed.
Small shops put out this type of work. Probably not more than a half dozen workers to make the 1000 holsters needed to fill this contract would be my guess. People back in this era worked 12 hour days pretty consistantly.
Once the pattern and methods of construction were standardized it would go pretty smoothly. 1000 holsters for German Sattlers would be a very small order. Jerry Burney
